The compounds described herein are useful for the treatment of diseases resulting from changes in splicing processes.

Viruses, in particular from the retroviral family, are one of the major causes of diseases around the world. Three subfamilies can be distinguished within the retroviral family: the oncoviruses, the lentiviruses and the spumaviruses.

The oncoviruses are thus termed because they can be associated with cancers and malignant infections. There may be mentioned, for example, leukemogenic viruses such as the avian leukemia virus (ALV), the murine leukemia virus (MULV), also called Moloney virus, the Abelson leukemia virus, the murine mammary tumor virus, the Mason-Pfizer monkey virus (or MPMV), the feline leukemia virus (FELV), human leukemia viruses such as HTLV1 (also, named HTLV-I) and HTLV2 (also named HTLV-II), the simian leukemia virus or STLV, the bovine leukemia virus or BLV, the primate type D oncoviruses, the type B oncoviruses which are inducers of mammary tumors, or oncoviruses which cause a rapid cancer (such as the Rous sarcoma virus or RSV).

Although the term oncovirus is still commonly used, other terms can also be used such as Alpharetrovirus for avian leukosis virus and Rous sarcoma virus; Betaretrovirus for mouse mammary tumor virus; Gammaretrovirus for murine leukemia virus and feline leukemia virus; Deltaretrovirus for bovine leukemia virus and human T-lymphotropic virus; and Epsilonretrovirus for Walleye dermal sarcoma virus.

The spumaviruses manifest fairly low specificity for a given cell type or a given species, and they are sometimes associated with immunosuppressive phenomena; that is the case, for example, for the simian foamy virus (or SFV), also named chimpanzee simian virus, the human foamy virus (or HFV), bovine syncytial virus (or BSV), feline syncytial virus (FSV) and the feline immunodeficiency virus.

The lentiviruses, such as Human Immunodeficiency Virus (HIV, also known as HTLV-III or LAV for lymphotrophic adenovirus and which can be distinguished within HIV-1 and HIV-2), are thus named because they are responsible for slow-progressing pathological conditions which very frequently involve immunosuppressive phenomena, including AIDS. Among the lentiviruses, the visna/maedi virus (or MVV/Visna), equine infectious anemia virus (EIAV), caprine arthritis encephalitis virus (CAEV), simian immunodeficiency virus (SIV) can also be cited. Certain indole derivative compounds such as ellipticine derivatives and aza-ellipticine derivatives are already known as intercalating molecules for correcting dysfunctions in gene expression, notably in DNA replication. They have been more specifically described for treating diseases such as cancer, leukemia or AIDS (see in particular patents FR 2 627 493, FR 2 645 861, FR 2 436 786).

Intracellular splicing consists of eliminating introns in pre-messenger RNAs to produce mature messenger RNAs that can be used by the translation mechanism of the cell (SHARP, Cell, vol. 77, p. 805-815, 1994). In the case of alternative splicing, the same precursor can be the source of messenger RNAs coding for proteins with distinct functions (BLACK, Annu. Rev. Biochem. vol. 72, p. 291-336, 2003). The precise selection of 5′ and 3′ splicing sites is thus a mechanism that generates diversity and that can lead to the regulation of gene expression according to the type of tissue or during the development of an organism. The factors involved in this selection include a family of proteins called SR, characterized by the presence of one or two RNA recognition motifs (RRM) and a domain rich in arginine and serine residues called an RS domain (MANLEY & TACKE, Genes Dev., vol. 10, p. 1569-1579, 1996). By binding to short exon or intron sequences of the pre-mRNA, called ESE (exonic splicing enhancer) or ISE (intronic splicing enhancer), SR proteins are able to activate, in a dose-dependent manner, sub-optimal splicing sites and to enable the inclusion of exons (GRAVELEY, RNA, vol. 6, p. 1197-1211, 2000). The activity of an SR protein in alternative splicing is specific insofar as the inactivation of the corresponding gene is lethal (WANG et al., Mol. Cell, vol. 7, p. 331-342, 2001).

Sequencing of the human genome and analysis of EST (expressed sequence tag) banks has revealed that 65% of genes are expressed in the form of alternatively spliced variants (EWING & GREEN, Nat. Genet., vol. 25, p. 232-234, 2000; JOHNSON et al., Science, vol. 302, p. 2141-2144, 2003). This mechanism is thus a favored target of modifications that can affect the factors involved in regulating splicing and of mutations that affect the sequences necessary for this regulation. At present, it is estimated that roughly 50% of the point mutations responsible for genetic diseases induce aberrant splicing. These mutations can interfere with splicing by inactivating or creating splicing sites, but also by modifying or generating regulating elements such as splicing enhancers or splicing silencers in a particular gene (CARTEGNI et al., Nat. Rev. Genet., vol. 3, p. 285-298, 2002; TAZI et al., TIBS, vol. 40, p. 469-478, 2005).

The strategies currently developed to correct these splicing defects rest on the use of various types of molecules (TAZI et al., cited above, 2005).

One strategy aimed at developing novel molecules to correct or eliminate abnormal splicing, for example, rests on the overexpression of proteins that interfere with this type of splicing (NISSIM-RAFINIA et al., Hum. Mol. Genet., vol. 9, p. 1771-1778, 2000; HOFINANN et al., Proc. Natl. Acad. Sci. U.S.A., vol. 97, p. 9618-9623, 2000).

Other strategies rest on the use of antisense oligonucleotides (SAZANI et al., Nat. Biotechnol., vol. 20, p. 1228-1233, 2002; SAZANI & KOLE, Prog. Mol. Subcell. Biol., vol. 31, p. 217-239, 2003) or of PNA (CARTEGNI et al., Nat. Struct. Biol., vol. 10, p. 120-125, 2003) enabling, respectively, the inhibition or activation of a splicing event.

Yet another strategy rests on the identification of compounds that influence the splicing efficiency of the pre-mRNA of interest (ANDREASSI et al., Hum. Mol. Genet., vol. 10, p. 2841-2849, 2001).

Lastly, a strategy based on the use of trans-splicing to replace mutant exons has been described (LIU et al., Nat. Biotechnol., vol. 20, p. 47-52, 2002).

One of the disadvantages of the developed strategies cited above to correct or eliminate abnormal splicing is their production cost. Indeed, the cost of producing antisense oligonucleotides that must be modified to improve their stability, and that of PNA molecules, is high.

Another disadvantage of the developed strategies cited above is that they require the use of expression vectors, such as, for example, for the strategy based on the use of trans-splicing.

International application WO05023255, under French priority of applications FR0310460 and FR0400973, filed by the Applicant, disclosed the use of indole derivatives to treat diseases related to the pre-messenger RNA splicing process in the cell.

Thus it was recently shown that certain indole derivatives prove particularly effective in treating metastatic cancer and in treating AIDS (BAKKOUR et al., PLoS Pathogens, vol. 3, p. 1530-1539, 2007).

However, the compounds described have a flat structure with four rings that have the disadvantage of intercalating between DNA bases and can thus lead to cellular toxicity.

In order to minimize the risk that these indole derivatives intercalate between DNA bases, the inventors developed novel compounds that are particularly effective in treating diseases related to the splicing process, but which, in a surprising manner, have a cellular toxicity that is clearly less than the indole derivatives of the prior art. In addition, these compounds are able to selectively inhibit certain splicing events.

According to route (A), the compound of formula (III) is placed in a protic solvent such as tert-butanol. The compound of formula (IV) is then added in a 1.1 molar ratio with respect to the compound of formula (III) in presence of Cs₂CO₃, in a 2.8 molar ratio, in the presence of Xantphos (4,5-Bis(diphenylphosphino)-9,9-dimethylxanthene), in a 2 mol % amount relative to the total amount of compound of formula (III), and in the presence of Pd(OAc)₂, in a 2 mol % amount relative to the total amount of compound of formula (III). The reaction mixture is then heated at 90° C., and stirred during 20 hours, under argon. The reaction mixture is concentrated under reduced pressure and the resulting residue is diluted with ethyl acetate. The organic phase is then washed twice with water, dried on magnesium sulphate, filtered and concentrated under reduced pressure. The residue could then be purified by column chromatography on silica gel to yield pure compounds (6), (43), (77), (80), (90), (112) and (136).

To a solution of halogeno compound (0.5 mmol, 1 equiv) in tert-butanol (2 mL) were added the amino moiety (0.55 mmol, 1.1 equiv), Cs₂CO₃ (456 mg, 1.4 mmol, 2.8 equiv), Xantphos (4,5-Bis(diphenylphosphino)-9,9-dimethylxanthene) (5.8 mg, 0.01 mmol, 2 mol %), Pd(OAc)₂ (2.2 mg, 0.01 mmol, 2 mol %). The reaction mixture was heated at 90° C. and stirred for 20 h under argon. The reaction mixture was concentrated under reduced pressure. The residue was purified by column chromatography on silica gel to yield pure compounds.

For example this procedure permitted to synthetize the following compounds:

Pharmalogical Data

The compounds of the disclosure have been the subject of pharmacological tests which have demonstrated their relevance as active substances in therapy and in particular for preventing or treating the infection of an individual, preferably a human, by a retrovirus and/or for preventing, inhibiting or treating a disease caused by retroviruses.

Example 9: Development of IDC16 Derivative Compounds

The inventors have shown that compound IDC16 (BAKKOUR et al., cited above, 2007) interacts functionally with the SF2/ASF complex and thus contributes to blocking alternative splicing during HIV replication, leading to the termination of the production of Tat protein.

Accordingly, the family of polycyclic indoles, to which compound IDC16 belongs, is known to exhibit the properties of DNA intercalating agents. Such compounds thus present a risk in terms of undesirable side effects.

The inventors thus sought to develop novel molecules exhibiting activity comparable to IDC16, in terms of activity inhibiting HIV splicing, but while not exhibiting the characteristics of DNA intercalating agents.

In their initial hypothesis, the inventors considered that the two polar heterocycles at the two ends of compound IDC16 were associated with its activity and that the two median rings were of less importance.

Based on this hypothesis, the inventors considered that:

-   -   the nitrogen of the indoline and of the D ring of IDC16 might         act as acceptors of hydrogen bonds;     -   the N-methylated 4-pyridinone motif might be preserved in the         analogues;     -   the flat tetracyclic geometry was not optimal and it might be         wise to replace the B and C rings by other motifs to limit DNA         intercalating properties.

Example 10: Inhibition of HTLV-1

The Human T-lymphotropic virus (HTLV) is a human RNA retrovirus that is known to cause a type of cancer. HLTV undergoes splicing to replicate.

To determine whether the compounds described above could act as HTLV inhibitors, a screen was performed on HUT102 (HTLV-1 chronically infected) cells.

Cells were plated at a density of 150 000 cells per well in 96 wells plates and treated daily with 10 μM of compounds for three days.

Cells were then harvested and an aliquot was used for cytotoxicity evaluation with Cell Titer (Promega).

The remaining cells was washed in phosphate buffer saline (PBS) and lysed for protein quantification with Bradford Assay (Sigma).

Then, HTLV Tax-1 protein expression was evaluated from 30 μg of total proteins by western blotting analysis.

Tax-1 expression was normalised by tubulin expression and related to control (DMSO treated) cells. Each compound was tested in triplicate.

Using the above described assay, compound 166 reduced Tax-1 expression by 80% when compared to control, suggesting that compound 166 has effective HTLV-1 inhibition capacity.
